Hi,

I’ve followed this doc, and hoped to find a solution with it, so I did’nt use the hosted-engine –deploy command, I’ve added a new host and at the end of the installation, the host stays unresponsive because unable to be attached to the same Storage volume .

Engine log :

Please check/post vdsm logs from the host. Thanks.

Hi,
I'd like to upgrade my oVirt environment from 3.5 to 3.6 and maybe 4, actually the manager oVirt is un 3.5 version, installed on a CentOS 7.2 and the two hypervisors are installed on CentOS 6.8.
I need anyway to upgrade the hosts to be able to move to 3.6.
I've tried to upgrade the first host, but I had of course issues telling that it can't be possible to mix different OS in the same cluster, I've also tried to create another cluster to put this host without success.
What is the best way to upgrade cleanly and safely ?
Thank you in advance for your advices

 

Follow this:

 

Simply ignore the steps that refers to the engine VM if you are with the engine on a physical system.
